Sue here:
I think it is absolutely that there are 2 prefects from each year, 
including 7th.  Which would mean there are prefects we have never 
even heard of.  If this is in fact the case then I would assume 
(dangerous, I know) that there was a person assigned to prefect duty 
from Percy's 7th year class, as he had taken on the job of Head Boy.  
that would also mean that Lupin remained a prefect through all three 
years even though James became Head Boy. And Ginny and Ron could 
absolutely by prefects at the same time.  Ron could be getting it 
from all directions with Ginny and Hermione wearing the badge!

This of course further feeds the fire over how many students there 
are at Hogwarts.  It would seem that perhaps there are approximately 
30 Gryffindors in Harry's year which would mean approx. 15 boys and 
15 girls.  That would mean that the Gryffindor Tower is HUGE!  Three 
dorm rooms per year, per sex; a total of 42 dorm rooms.  Which would 
mean the Griffendor tower has got to either be *very* tall or *very* 
fat.  

That would also mean that the house tables hold a total of 210 
students.  That of course gives JKR her total of approx. 1000 
students at Hogwarts.  If this is the case I sure wish she would 
explain why we have heard of so few of them!

Sue, who like a previous poster wonders why Draco was made a 
prefect.  Is the Slytherin class from this year *that* bad?
